Testing non-standard neutrino matter interactions in atmospheric neutrino propagation

open access: yes, 2016
We study the effects of non-standard interactions on the oscillation pattern of atmospheric neutrinos. We use neutrino oscillograms as our main tool to infer the role of non-standard interactions (NSI) parameters at the probability level in the energy ...
